Details on Asus’ newest tablet remain a bit thin, but the PadFone is certainly one of the more interesting devices — or pair of devices — to be shown off at Computex 2011 so far.

If the name itself and image weren’t enough clarification, the PadFone is a tandem consisting of a 4.3″ Asus Android smartphone and a 10.1″ tablet dock — which looks quite a bit like the Eee Pad Transformer. Flip the bay cover open on the back of the tablet, plug in to the phone’s HDMI and USB connectors, and you’re ready to rock — you’ll even be able to utilize the phone’s camera for rear-facing shots while docked thanks to a punch-0ut in the cover.

It’s a slick arrangement, since the phone packs the internal storage and 3G (or perhaps 4G) radios for both devices. That means you’ve only got to worry about keeping one device stocked with your favorite media files, data, and apps. And speaking of apps, we know the PadFone will run Android, but which version? While Asus wasn’t willing to confirm anything, a company rep told Engadget that “you can’t launch a smartphone with Honeycomb as the OS.” That could be a not-so-subtle hint that Asus plans to ship the PadFone with Ice Cream Sandwich, which would be a natural fit on a device like this since it’s intended to unify the Android tablet and smartphone platforms.

Other details about the PadFone remain fairly scant at this point, as Asus is still finalizing what hardware will make the cut. The company is targeting Q4 2011 for launch, so you should be able to get your paws on one just in time for the holiday season. Let’s hope there’s a bit more stock to go around than there was for the launch of the Transformer — which flew off shelves at $399 when they initially went up for sale.
